I know, right? It's like they started the 1st episode off pretty good, then had up and down phases until the final eppy. I heard somewhere that particular groups of animators were assigned for different episodes, and it shows. Sometimes the styles are good, particular 1, 5 and 25. But the bad art really shows.
Oh gosh, I know that one! I saw another one where Mel kicked a dog, but they drew his leg like a human leg. I could go on for hours!
